As a user:
- If I need the service and only intend to use it for a very small project, I love forever free plans. Because I know I can subscribe use your server time and forget my account forever. I often subscribe with a temp email so that I don't even receive your emails anymore.
- If I seriously need the service and is ready to pay for it, I don't really care about the free forever plan vs free trial vs paid trial.
As a business:
- Any time I have offered a free forever plan, basically 95% of the created accounts are dormant free accounts (like I personally am when I find the correct tool to scratch my itch). 4% are from people (usually from south east asia) creating hundreds/thousands of accounts (sometimes manually !) to circumvent the free plan limitations instead of just paying for the service. And 1% are from legitimate users/customers.
- People in the 95 and 4% categories still believe they are owed support. And if you don't give them an easy way to let them contact you, they now have twitter and facebook and business reviews websites to get to you. On top of emails, LinkedIn messages and yes, phone calls.
- Cutting the free accounts has almost no impact on real customers acquisition. You can let people experience your product with a temporary trial, that includes support and way more features, but behind the credit card screen. Extend the free trial as much as needed if people ask for it through your usual support channel. You will still get abusers but those are easier to detect, because they need to provide some payment details which are harder to fake, and after you shut them down for the third time in a row, they usually go away.
